根據關鍵時期理論,為什麼成年的學習者難以擁有道地的發音?
【Mia】評論
there are too many cases of adults who acquire adequate or good pronunciation in a second language through instruction and practice. While they will never be mistaken for native speakers, their efforts are rewarded by speech that is perfectly comprehensible.第二語言的練習和指導-- 獲得適當或好的發音,但不會被誤認為是在說母語

因為題目中有這句:"Proponents of this theory argue that the acquisition of native-speaker pronunciation in any language is biologically possible only until about the age of twelve"
